Updating An Old Technique

One Big Umbrella: In 2015 I had great success using a Westcott 7' Parabolic Umbrellas on a photo assignment in San Mateo's Japanese Garden. By placing the shoot-through umbrella in a path of the morning sun, I was able to produce an enormous softbox effect with no flash enhancements. 

Parabolic umbrellas were all the rage back then, as they supposedly provided the photographer with a more efficient design to concentrate the light more effectively. The dream was that speedlight users could get more "bang for your buck" when using their little flashes. While skeptical, I bought two, one shoot-through and one with a silver reflective interior, and decided to see if the hype was true. Right out of the gate I found the umbrellas difficult to control even in the most gentle of breezes. After some experimentation, I determined that the best way to secure the umbrella was to use two light stands clamped as far apart as the umbrella shaft would allow. While stable, I need a bunch of sandbags to keep them from swaying. Certainly it was effective, but so darn clumsy.

The only way this could be made to work (legally) in a public venue was to have Cissie hold the umbrella aloft on a monopod and  manually align the umbrella for maximum effect. I hope you'll agree that it was worth the effort, and I still consider this photo shoot one of my best efforts. As lovely as the shot was, I couldn't help but think that proper exposure for my subjects resulted in an overexposed background. Nobody has ever commented on it, but I know it's there, and find it very bothersome.

Fast forward to 2026. The assignment was to photograph the District Manager for California Water Service Bayshore District. (Cal Water). I knew Cal Water had a new facility just two blocks from where I used to work, and since there was an inner lot for storing emergency vehicles and equipment, I suggested that we make the shot with an outdoor background. I had scheduled the shoot for early to take advantage of the breezeless morning air, so I pulled my mega-umbrellas from storage and brought them, along with two twelve-foot light stands in case they both were needed. 

It was about 9:15 in the morning, and the air was relatively still. Ross, my subject, suggested that we lay out the contents of a typical "go bag", and use the San Mateo "Water Wagon" as a background. As luck would have it, the morning sun illuminated the wagon perfectly.

I started out by mounting the translucent white  umbrella on a light stand and aligning it to produce the largest possible shadow on the ground. You can see the shadow of a second light stand that was used to hold my speedlight key light. Notice that the props are placed well within the edges of the shadow. I purposely left a gap between the trailer tires and the far edge of the shadow (below left).

Next I positioned my subject so that his entire body is within the shadow. Notice that the fill lighting from the shoot through umbrella is very even, but a bit underexposed when compared to the background (above right).

This final shot was made with a small Lumiquest Softbox mounted on a lightstand about two feet to camera right. This gave the subject some three dimensionality and added some sparkle to the supplies in the foreground. His right foot has now been positioned within the shadow provided by the umbrella. If necessary, the umbrella could be moved slightly, but it is so much easier to position the umbrella and arrange everything else.

This technique can also be applied to making a headshot where the background needs to be handled differently. Had a head shot been required (sample, left), I could have used a smaller aperture (the shutter is set to 1/250 of a second (the fastest convention flash synchronization speed) and the key light moved closer to the subject to brighten the subject without any other adjustments. 

Never Let The See You Sweat: Behind the scenes there was a bit of unseen drama. My flash trigger failed to communicate with my key light, so I was forced to switch for the key light's radio receiver to an optical trigger which would be triggered by a shoe mounted speedlight. Some position changes had to be made, but once all of the adjustments were made, the session went smoothly. It turns out it was a depleted battery issue, and instead of changing them out, it was faster to revert to the optical mode. All this was done while keeping up the chatter on how well the session was going, while under my breath I occasionally muttered,  "That's odd".

Elapsed time from first test exposure (8:18 AM) to the last photo (8:31 AM) was 13 minutes.

 It was a good day.
